Go SDK for Permit.io

Instructions for installing Go SDK for interacting with Permit.io.

Overview

This guide will walk you through the steps of installing the Permit.io Go SDK and integrating it into your code.

Installation

Install the SDK using the following command:

go get github.com/permitio/permit-golang

Put the package under your project folder and add the following in import:

import "github.com/permitio/permit-golang/pkg/permit"

Usage

Init the SDK

To init the SDK, you need to create a new Permit client with the API key you got from the Permit.io dashboard.

First we will create a new Config object so we can pass it to the Permit client.

Second, we will create a new Permit client with the Config object we created.

package main

import "github.com/permitio/permit-golang/pkg/permit"
import "github.com/permitio/permit-golang/pkg/config"

func main() {
    PermitConfig := config.NewConfigBuilder("<YOUR_API_TOKEN>").Build()
    Permit := permit.New(PermitConfig)
}

Check for permissions

To check permissions using our Permit.Check() method, you will have to create a new User and Resource models using the enforcement models The models are located in github.com/permitio/permit-golang/pkg/enforcement

Follow the example below:

package main

import "github.com/permitio/permit-golang/pkg/permit"
import "github.com/permitio/permit-golang/pkg/config"
import "github.com/permitio/permit-golang/pkg/enforcement"

func main() {
    permitConfig := config.NewConfigBuilder("<YOUR_API_TOKEN>").Build()
    Permit := permit.New(permitConfig)

    user := enforcement.UserBuilder("user_id").Build()
    resource := enforcement.ResourceBuilder("resource_id").Build()
    permitted, err := Permit.Check(user, "read", resource)
    if err != nil {
        return
    }
    if permitted {
        // Let the user read the resource
    } else {
        // Deny access
    }
}

Sync users

To sync users to the Permit.io API, using the Permit.SyncUsers() method, you will have to create a User model using our main Models package. The models are located in github.com/permitio/permit-golang/pkg/models

Follow the example below:

package main

import (
    "additionalContext"
    "fmt"
    "github.com/permitio/permit-golang/pkg/config"
    "github.com/permitio/permit-golang/pkg/models"
    "github.com/permitio/permit-golang/pkg/permit"
)

func main() {
    ctx := additionalContext.Background()
    PermitConfig := config.NewConfigBuilder("<YOUR_API_TOKEN>").Build()
    Permit := permit.New(PermitConfig)

    newUser := models.NewUserCreate("new_user")
    user, _ := Permit.SyncUser(ctx, *newUser)
    fmt.Println(user.Key)
}
